Somatic effects from cannabis inhalation or ingestion might include: reddening of the eyes, dry mouth and throat, appetite stimulation, heightened sensory experiences, elevated heart rate, fluctuations in blood pressure, altered balance and stability, muscle relaxation, pain relief, antiemetic effect, anticonvulsant, and drowsiness or restlessness (Katzman, 2018)
Psychological effects of cannabis use include: psychoactive effects or "high," feelings of well-being, sociability, relaxation or stress reduction, and altered perception (Katzman, 2018)
Cannabis has been associated with disruptions in memory, confusion, impaired abilities (i.e., concentration, attention, reaction), and anxiety (Katzman, 2018)
High doses of cannabis have been associated with paranoia, hallucinations, delusions, ataxia, and in some cases dissociative states (Katzman, 2018)
Some long-term effect studies have identified impairments in memory, concentration, and cognitive abilities (i.e., decision making, judgement) (Katzman, 2018)
Frequent and prolonged cannabis use has also been shown to increase the risk for psychological (anxiety) and physical dependence, as well as addiction (Katzman, 2018)
